Title: Scribing method for sos wafer
Inventor: TAKEUCHI BUNJI
IPC: H01L21/78
Filed: 1982-07-19
Abstract: PURPOSE:To enable to scribe a SOS wafer of a large plate thickness at a high speed and without covering a protection film by a method wherein the process of forming the first scribing groove in the surface of the SOS wafer and the process of forming the second one in the back surface are provided. CONSTITUTION:In the first process, scribe scanning is performed as arrow marks on the surface of the SOS wafer 8 with a diamond point, resulting in the formation of the first scribing groove 9 in lattice form. In the second process, while detecting the first scribing groove 9 in the surface of the SOS wafer 8, the back surface of said SOS wafer 8 is so irradiated with CO2 laser by a laser scribing device that the laser runs along the first scribing groove 9, resulting in the formation of the second scribing groove 10. Thereafter, the division of the SOS wafer 8 is performed by a normal means. Even a SOS wafer of the plate thickness of approx. 600mum can be so scribed that the chip dimensional accuracy after division becomes better, and a protection film is unnecessitated at the time of scribing.

Filed: 1986-05-30
Abstract: PURPOSE:To obtain a natural liquid crystal display panel excellent in display quality, by making selection timings of scan electrodes in adjacent split areas symmetrical, centering around the adjacent scan electrodes between the adjacent split areas. CONSTITUTION:Outputs R1-R3 of a scan electrode driving circuit 105 are connected to scan electrodes T1 and T6, T201 and T501, and T3 and T4, respectively. The outputs of the scan electrode driving circuit 105 are connected to the scan electrodes so that they become symmetrical centering around the scan electrodes T3, T4 being adjacent in a boundary of the upper side picture and the lower side picture. As a result, the scan electrodes T3, T4 are selected simultaneously, and in the same way, the upper side picture and the lower side picture are selected symmetrically centering around the scan electrodes T3, T4, therefore, the discontinuity of a display quality caused by a timing by which the scan electrodes being in the vicinity of the boundary of the pictures, such as the scan electrodes T3, T4 are selected is dissolved.

Title: Method and device for single frequency simplex radio data communication
Inventor: UMAGOE TOSHIYOSHI
IPC: H04B1/54
Filed: 1995-04-26
Abstract: PURPOSE: To prevent crosstalk in advance by allowing either one of the two radio stations to send a transmission radio wave within the transmission/ reception changeover period of the two stations. CONSTITUTION: A radio station 1 sends a signal denoting the end of data transmission to the end of data and a radio station 2 receives the data transmission end signal and sends data after the elapse of a transmission rise time t1 . The transmission from the radio station is continued even for the time t1 and then the transmission is interrupted and the reception is made after elapse of a reception rise time t2 . Then the radio station 2 does not send data for a period of the time t2 and sends data after the elapse of the time t2 . Since either of the radio stations 1, 2 sends a radio wave even during the operation time for changeover of transmission and reception between the two radio stations making communication, the busy state of the radio frequency is surely detected.

Abstract: PURPOSE:To improve the efficiency of simulator operation and to automate the training applied to a simulator by deciding the rationality of the instruction for multifunctions or state change from an instruction console by a device for deciding the rationality of input value. CONSTITUTION:The operator's operation signal in a mimic control panel 1 is made into the input signal to a plant mimic computer 3 through an input/ output device 2 and the computer 3 computes plant operations by using the plate data of a memory device 4.

The timing for the state change is created by an input medium such as keyboard of the console 5 when a trainer is going to execute the multifunctions or the state change at this time. The conditions are subjected to decision by calling the rationality criteria set for each of the multifunctions from the memory device 7 in the device 6 for deciding the rationality of input value and if the criteria are satisfied, the conditions are applied to the computer 3. The non-rationality is announced to the console 5 if the criteria are not satisfied.

Title: Recorder
Inventor: KAN FUMITAKA
IPC: B41J2/33
Filed: 1987-05-25
Abstract: PURPOSE:To reduce running cost and prevent ghost or the like from being generated, by forming an ink part energized in one direction and then an ink part energized in the opposite direction, by an energy-applying means. CONSTITUTION:Of an ink transferred by a print-transferring roll 1, undeveloped ink 2a' is again brought to a part for contact with an intermediate transfer roll 6 before recovering a crosslinked structure when the rotating speed of the roll 1 is high, resulting in that the ink 2a' is developed as ghost. To avoid this, at the time of energizing a recording electrode 5, an electric current is once passed in one direction and then immediately passed in the opposite direction by applying a voltage, whereby pH of an image part is greatly changed, and a non-image part 2c with pH greatly changed in the opposite direction is formed subsequent to a part 2b with the crosslinked structure broken. Therefore, the ink 2a' is again contained into an ink container 3, and its restoration is speedily performed. Thus, generation of ghost or the like is prevented, and trailing of an image is prevented from being caused by rubbing by the electrode 5 of the image part in which the viscosity of the ink is lowered.

Title: Speed change gear
Inventor: YAMAURA SHIYOUICHI
IPC: F16H3/74
Filed: 1982-07-20
Abstract: PURPOSE:To permit smooth change of the number of revolution by forming a stepless speed change gear in combination of a differential gear and a fluidic clutch and increasing the starting torque on an output side. CONSTITUTION:Revolution is applied onto a driving shaft 1. When a differential shaft 8 is not applied with a load, said differential shaft 8 revolves with the equal number of revolution to that of the driving shaft 1. When the differential shaft 8 is applied with a load, a revolution lag is generated on a left-side gear 4 with respect to a differential case 2, and small differential gears 3 and 3' make self-rotation as well as revolution. In this case, also a right-side gear 5 makes self-rotation as well as revolution so a slippage as in a fluidic clutch is generated between a driving vane 6 and a responsive vane 6.

Abstract: PURPOSE:To constitute a logic circuit of fewer number of transistors(TR) than the conventional one, and to miniaturize it by constituting the circuit of total four TRs, i.e., two for constituting a serial circuit body, and two for constituting an invertor circuit. CONSTITUTION:Since a first input terminal 1 is connected to one end of the serial circuit body 7, and at the same time, is connected to another end of the serial circuit body 7 through the invertor circuit 3, the signals of 0.1 or of 1.0 are given to both ends of the serial circuit body 7 according to the signal to be inputted from a first input terminal 1.

Title: Multi stage hydraulic machine

IPC: F03B3/10
Filed: 1981-08-14
Abstract: PURPOSE:To reduce downward thrust caused by a runner by introducing high pressure water in a back pressure chamber of any stage to one side of a water thrust adjusting disk provided on the main shaft and installing a seal on the other side of the disk and producing a differential pressure between both ends of the disk. CONSTITUTION:The water in a back pressure chamber 13 of a high pressure runner 1 is introduced to a high pressure chamber 143 of a water thrust adjusting disk 140 provided on the main shaft 2 by a bore 141 opened on the main shaft 2 and flows to a low pressure chamber 144 through a seal 142 and further flows to a runner exit 40 through a pipe 155. When passing through the seal 142, the water having entered the high pressure chamber 143 is subject to pressure drop and hence produces a differential pressure between the high pressure chamber 143 and the low pressure chamber 144 of the disk 140. As a result, a thrust acting in the upward direction is generated at the disk 140. A downward thrust produced by a high pressure stage runner 1 and a low pressure stage runner 21 is balanced by an upward thrust generated by the disk 140, thereby reducing a downward thrust acting on a bearing 28 of the main shaft.
